Eight roadside surveys for raptors were conducted in southwestern New
Mexico from May 1988-January 1989 to examine seasonal abundance and ha
bitat use. Of the 17 species observed, American kestrels (Falco sparve
rius), red-tailed hawks (Buteo jamaicensis), turkey vultures (Catharte
s aura), and northern harriers (Circus cyaneus) were most common and o
ccurred along the entire survey route in all habitats. Bald eagles (Ha
liaeetus leucocephalus) were recorded less frequently only in January
in riparian habitats and pinyon-juniper and Ponderosa pine ecotones, a
nd Swainson's hawks (B. swainsoni) were infrequently observed in mesqu
ite grasslands and Chihuahuan desertscrub in May and July. Golden eagl
es (Aquila chrysaetos), ferruginous hawks (B. regalis), prairie falcon
s (R mexicanus), and Cooper's hawks (Accipiter cooperii) were also rec
orded infrequently but occurred widespread along the survey route.
